Along with Miley, her li'l sis, Noah Cyrus, her poppa, Billy Ray Cyrus, momma Tish, and older bro Trace, older sis Brandi, and younger brother, Braison, were all beating the heck out of each other under their Christmas tree, and we've got the picture to prove it!

Provided by none other than Miss Miley herself!

Along with the HIGHlarious pic of them (above), she wrote:

"annual family fist fight 👊💥🎅"

We think our favorite moment of this fight is seeing Miley's "Mammie" pulling her hair in the background!! Everyone else seems to be kind of faking it, but that looks like one strong and firm grip!

And, if you think she looks familiar, that's because she's the same grandmother that Miley got a tattoo of her on her arm last month!

Oh, and if you wanna see more pics from the Cyrus Christmas family gathering, check 'em out (below), including one AH-MAZING throwback pic that Miley posted! Times have certainly changed, haven't they???
